Let's revisit our lucky_number function. We want to change it, so that instead of printing the message, it returns the message.

This way, the calling line can print the message, or do something else with it if needed. Fill in the blanks to complete the code to make it work.
def lucky_number(name):
number = len(name) * 9
___ = "Hello " + name + ". Your lucky number is " + str(number)
___

print(lucky_number("Kay"))
print(lucky_number("Cameron"))

Answer:

Replace the first blank with:

message = "Hello " + name + ". Your lucky number is " + str(number)

Replace the second blank with:

return message

Explanation:

The first blank needs to be filled with a variable; we can make use of any variable name as long as it follows the variable naming convention.

Having said that, I decided to make use of variable name "message", without the quotes

The next blank is meant to return the variable on the previous line;

Since the variable that was used is message, the next blank will be "return message", without the quotes

   // main method to begin program execution

   public static void main(String[] args) {

       // scanner object scan is declared

       Scanner scan = new Scanner(System.in);

       // Prompt the user to enter a number

       System.out.println("Enter the number of stars you want: ");

       // user input is assigned to numOfStar

       int numOfStar = scan.nextInt();

       // call the makeStars method

       makeStars(numOfStar);

   }

   

   // makeStars method print stars using recursion

   // the method call itself till starNum == 0

   public static void makeStars(int starNum){

       if (starNum != 0){

           System.out.print("*");

           makeStars(starNum -1);

       }

   }

}

Explanation:

The code is well comment and solve the problem using recursion.

Suppose your company has decided that it needs to make certain busy servers faster. Processes in the workload spend 60% of their
vekshin1

Answer:

CPU need 50% much faster

disk need 100% much faster

Explanation:

given data

workload spend time CPU  = 60%

workload spend time I/O = 40%

achieve overall system speedup = 25%

to find out

How much faster does CPU need and How much faster does the disk need

solution

we apply here Amdahl’s law for the overall speed of a computer that is express as

S = \frac{1}{(1-f)+ \frac{f}{k} }      .............................1

here f is fraction of work i.e 0.6 and S is overall speed  i.e 100% + 25% = 125 % and k is speed up of component

so put all value in equation 1 we get

S = \frac{1}{(1-f)+ \frac{f}{k} }  

1.25 = \frac{1}{(1-0.6)+ \frac{0.6}{k} }  

solve we get

k = 1.5

so we can say  CPU need 50% much faster

and

when f = 0.4 and S = 125 %

put the value in equation 1

S = \frac{1}{(1-f)+ \frac{f}{k} }  

1.25 = \frac{1}{(1-0.4)+ \frac{0.4}{k} }  

solve we get

k = 2

so here disk need 100% much faster
